Application filed December 4, 1915. Serial No. 65,014.

T 0 all 211710722 it may Ponce/"22 Be it known that 1. Mann. BLACKMAN, a citizen of the United States, and a resident of the city of New York, borough of Manhattan. in the county and State of New York. have invented a new and Improved T alking-Machine-Xeedle Magazine, of which the following is a full, clear,'and exact description.

Among the principal objects which the present invention has in view are: to provide means for carrying a number of needles for use on talking machines, and to regulate the delivery thereof; and to provide a simple device which may be employed as an attachment to sound boxes of conventional construction for talking machines.

Drawings-Figure l is a side view of a fragment of a tone tube and a sound box of conventional construction mounted thereon and equipped with a magazine constructed and arranged in accordance with the present invention; Fig. 2 is an end view of the same; Fig. 3 is an enlarged detail view in section showing a lower end fragment of the magazine and a portion of the sound box on which the same is mounted; Fig. 4 is a detail view,

of the magazine.

Description-As seen in the drawings, a sound box 8 has adiaphragm 9, to the center of which is attached the vibrator 10. The vibrator 10 is rigidly connected with arocking table 11, whichis supported on the knife blades 12 and held pressed thereon by the springs 13 and the retaining screws 14 holding the said springs. Extended from to which is directly and rigidly connected the vibrator 10. Also directly and rigidly connected with the bracket 15, is a chuck 16. The chuck 16 is a split-ended tube, having a collar 17 and a chuck head 18. An upward continuation of the tube forming the chuck 16, is the magazine 21.

The magazine 21 is a straight tube wherein are placed the needles A used in a talking machine employing record disks. The ma azine is made of any suitable length and is closed at the upper end thereof by a screwe cap 22 is removed Whenever it becomes necessary to charge the magazine 21, and is replaced after said magazine is charged.

To steady the magazine without restraining the vibration thereof which is imparted 'sively, the

)illtlV in section showim a modil a s to the vibrator 10 from the needle in the chuck 16, a bracket 23 is provided mounted on the sound box, using for this purpose, a screw 2%, or other suitable device, The opening in the bracket :23 is such as to permit the magazine to oscillate in said opening.

The feed of the needles is controlled by a spring check 19. the crotched end 20 of which is extended inside the chuck 16, a suitable opening being formed to pass the same. Normally the end 20 is disposed in the path of the needles A, to engage and prevent the downward travel of the same.

To remove the check 19 and the end 20 from engagement with the needles succesupper end of the chuck head is beveled to wedge under the overhang 19 of the said check. This action is completed only when the jaws of the chuck 16 are closed. This prevents the needles from passing through the chuck. To adjust each needle. the head 18 is manipulated to partly open the jaws of the chuck 16 and to allow the needle to pass therethrouglu The operator catches and adjusts the needle when the end extends from the chuck. lVhen the head 18 is thus manipulated to release the needle being adjusted, the end 20 is permitted to engage the next succeeding needle. The said succeeding needle is thus held while the needle being arranged for service is being adjusted.

0peration.-Having a magazine constructed as above described and as shown in the accompanying drawings,,the operation of filling the same begins by setting up the chuck head 18 suiiiciently to prevent the passage of needles A therethrough. The first needle dropped will be arrested at the bottom of the magazine by the end 20, the spring 19 having been advanced so that the end engages said needle. \Vhen the magazine has become completely charged, the cap 22 is replaced so that the sound box 8 may be moved to any angle without fear of dumping or losing the needles contained in the magazine. The end 20 is now retracted and the chuck 16 arrests the first of the needles A. The head 18 is manipulated to allow the said needle to extend beyond the end of the chuck to the required or adjusted position. The spring and end 20 are then released, the latter engaging the second needle, While the chuck be used, holding the same firmly in service 16 grasps the first, or needle to position. When it becomes necessary to The magazine 21 may be extended to any stiitable length to carry any desired number.

of-lnee'dles. It is obvious that needles may be quickly emptiedfrom or placed within the magazine, and-that after having been placed the renewal of the needles will be accomplished at a great saving of time and with added facility.

' Modz'ficati0n.--I11 the modified form of the invention shown in Fig. 4 of the drawings, the magazine 21 is replaced by a case 25. longitudinal in cross section. The case Qlihas a closing cap 26, which is removed Qhen the magazine is to be charged with the needles A. Resiliently mounted on the case 25, is a spring 27', the thrust end 28 whereof it? isex-tended into the path of the lower end needle A. When the thrust end '28 is depressed, it bears upon the end needle to move the'same into the chuck for holding the said needle in service, the chuck head 18 having been released'to permit the expansion of t hejaws ofsaid chuck.

While the end needle is being delivered to the chuck and chuck head 18, it will be be)! at thh Patent may be obtained in five cent! each,

noted that the end 28 extends into the path of the succeedingneedles-and prevents the delivery thereof until the end 28 having been released, the spring 27 lifts it to the normal position beyond the path of the said needles, and as. shown in Fig. 4.- of the drawings. i

' Claims: v

1. An apparatus as characterized comprising an open-ended tubular magazine, a chuck in open communication with and dis posed at the delivery endof said magazine; a head for contracting and expanding said chuck; a resilient check member mounted on said magazine and having a portion.thereof extending within the same to normally support a column of needles in said magazine; and means lifting said check member from engagement with said needles, said means embodying said head and an inclined portion of said check member, whereby said check member is lifted when said head closes said chuck. i

'2. In combination with a sound box, a magazine comprising a diaphragm vibrator having rigidly mounted thereon, a corn tractible chuck; a contracting chuck head for said chuck; an elongated tubular magazine structurall connected with said chuck and supported hereby; an additional support embodying a bracket rigidly secure said sound box; and a closure cap for said magazine.
